JASPER GRISSIM, 0F PHILADELPHIA, PENNSYLVANIA.

COLLAPSIBLE AVNING OR CANOPY FOR CHAIRS.

To all whom it may concern Be it known that I, JASPER GRISSIM, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Collapsible Awnings or Canopies for Chairs, of which the following is a specification.

My invention relates to new and useful improvements in collapsible awnings or canopies for chairs, and has for its object to provide an exceedingly simple and effective device of this character to be used in combination with a chair which may be readily and quickly applied to the back of a chair so that the person occupying said chair will be shaded from the rays of the sun.

A further object of the invention is to produce an awning or canopy which is adapted to be mounted upon a chair, but when not in use to be folded back out of the way.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may under-- stand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specification, in which- Figure 1, represents a rocking chair showing my collapsible awning applied thereto, the cover or canopy portion thereof being shown in section. Fig. 2, a plan view of the cover or canopy showing the tucks in which are inserted portions of the frame, the side flanges being removed. Fig. 3, a side elevation of the foraminous canopy, the skirt being shown in section and a portion thereof being broken away. F 4, a perspective view of the frame, showing the relation of one part to the other. Fig. 5, a side elevation of my improvement as applied to another form of chair, a portion of the foraminous skirt being broken away; and Fig. 6, a face view of a portion of the Specification of Letters Patent.

frame illustrating the construction used when applied to certain styles of chairs. Fig. 7 is a side elevation of a chair showing my collapsible awning folded back to the position it assumes when not in use. Fig. 8, an edge view of a slightly modified form of frame and means to attach it to the chair. Fig. 9, a face view thereof. Fig. 10, an edge view of a still further modified form of my invention.

In carrying out my invention shown in Figs. 1 to 4 inclusive, 2 represents a chair having a relatively high back, and to the side posts of the back are secured the upright frame 3 and extension frame 4:. The upright frame is preferably formed from a single piece of metal bent to produce a top rail 5 and arms 6, each of which is provided with a hole 7 near its end and also having a notch 8 produced intermediate its length. The extension frame lis also preferably formed of a single piece of metal bent to form a front rail 9 and the parallel arms 10, each of which is provided with a perforation 11 near its end. The perforations 7 and 11 in the arms (3 andlO are brought into alinement and through these pass an attaching screw or its equivalent 12 which is threaded into the side posts of the chair back some distance from their upper ends and when the awning is open and in use, the notches 8 will engage the shank of the stop screws 13 knotted in the side posts of the chair back and limiting the forward movement of the frame. The frame members are covered by a canopy 14: which consists of a top 15, side walls 16 and front and back llaps l7 and 18 respectively. From the canopy are formed the tucks 19 into which are inserted the frame members before they are fastened to the chair. When the awning is in place upon the chair, the extension member l. of the frame will be held at the desired distance from the upright member of the frame by the canopy, the upright member of the frame will be held in its proper position by its contact with the stop screws 13. Since the parts of the frame are within the canopy, as the extension mcn'iber is moved rearwardly it will cause the canopy to follow with it and at a certain point will disengage the upright member from the stop screws 13 and will cause said upright member to move backward until the whole of the awning hangsdown from the attaching screws 12 at the back of the chair.

If at any time while the awning is in use, the wind is blowing at a suflicient velocity to raise the awning or cause it to shake, it may be tied down by suitable attaching cords 20, one end of which passes through the perforation in each of the arms of the extension member and the opposite end'tied to the chair, preferably the arm thereof. As here described, I have produced an awning to shade the suns rays from the person using the chair and to overcome any possibility of being troubled with any insects flying about, a foraminous canopy 25 may be placed in the position which comprises the top or cover 22 of foraminous material of the same size as the top of the'canopy 14L, and this cover is provided with a set of hooks 23 which fasten into the eyes 24: sewn to the outside of the top of the canopy 14. The skirt of this foraminous canopy 25 is of foraminous material such as mosquito netting and each of the sections is a cord, so that no material will be gathered where it is sewn to the cover 22, although the bottom thereof will be suiiiciently wide to permit uninterrupted movement of the person using the chair.

In Figs. 5 and 6 I have shown a slightly modified form of my invention so produced as to be applicable to chairs with leaning backs and when used with such chairs it is necessary to drop the front end of the awning in accordance with the backward movement of the chair to keep the awning on a horizontal line. In accomplishing this I form a slot 26 in the end of each of the arms of the extension member of the frame so as to permit thebackward movement of the extension member which will lower the front end of the awning the desired distance. In other respects this form of my device is the same as that shown in Fig. 1.

In Figs. 8 and 9, I have shown a further modified form of my invention which will permit the awning frame to be readily and quickly adjusted to change the position of the front edge of the awning in accordance with the position of the chair back, so that the awning will rest in a generally horizontal line. 27 denotes a plate of any desired configuration having screw receiving holes 28 countersunk, to receive the heads of the screws 29, whereby the plates are attached to the side rails of the chair back. In this form of my invention, I utilize the upright frame 3 and the extension frame 4 these being pivoted to the plate 27 in any desired manner here shown as being a butterfly bolt 30. Said bolt passing through the end of the extension l to the upright frame 3 some distance from the end of the latter. The ends of the arms ..6 .of the upright frame are each provided with a perforation 31 which aline with the perforations 32, produced in the plate 27. Nhen the desired adjustment of the awning has been obtained, a pin 33, is passed through the perforation 31 and into one of the perforations 32 which will hold the frame in the determined position. I In Fig. 10, I have shown a plate 27 simi lar to the one illustrated in Figs. 8 and 9 which is provided with a central projection 34: having radial serrations which register with the radial serrations 36 formed upon the face of the projection 37 produced with the plate 38. Said plate being attached to the upright frame 3 by rivets or other suitable members 39. A bolt 40 having its'head countersunk in the plate 27 passes through said plate. The plate 38 and the arms of both frames and said bolt as a butterfly nut 41 threaded thereon to draw the parts securely together and hold them in the different adjusted positions. To change the adjustment,the end 41 is backed OK the bolt a short distance to permit the disengagement of the serrations upon the projections which permits the frame to be moved about. Of course I do not wish to be limited to the exact details of construction as here shown, as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful, is-

1. In combination with a chair, a frame comprising an upright member and an extension member, each ofsaid members being bent from a single piece of metal to produce a rail and parallel side arms, means for securing the ends of said arms to a chair, a canopy covering the frame, and stops carried by the side posts of the chair back with which the upright member of the frame will contact to limit the forward movement of the awning. V

2. In a collapsible awning for chairs, the combination with a chair of an upright frame formed from a single piece of metal bent to produce a rail and parallel side arms, means for pivoting the ends, of the side arms of said upright frame to the back of a chair, said arms having notches formed therein between their pivoted ends and the rail, an extension frame also formed from a single piece of metal bent to produce a rail and parallel side arms, the ends of which are pivoted by the same means as the upried by the back of the chair co-acting with notches in the arms of the upright frame In testimony whereof, I have hereunto for limiting the forward movement of the aflixed my signature in the presence of two 10 upright frame, a canopy secured upgn the subscribing Witnesses.
